Sometimes you may get an error that Wells Fargo is missing a bank statement even though it is connected and there are no bank connection breakages. 

Why is this so?

When your client adds Wells Fargo to Ledgersync there is an option to  "Add Bank Statement" fetch. The client has to essentially authorize this.

If they do- you'll get bank statements, if not an error will appear " that the client has not authorized bank statements"
